 feat: add Rust binary calculator example 
First example of the binary server type — a compiled Rust MCP server
packaged as an MCPB. Based on the official Rust SDK calculator example
(rmcp 1.2.0, 2 tools: sum/sub, ~80 LOC).

Includes Cargo.toml, Dockerfile for Docker-based builds, .mcpbignore
to exclude source from the bundle, and README with build/pack/test
instructions.

MCPB Examples

This directory contains example MCP Bundles that demonstrate the MCPB format and manifest structure. These are reference implementations designed to illustrate how to build MCPB extensions.

⚠️ Not Production Ready

Important: These examples are NOT intended for production use. They serve as:

  • Demonstrations of the MCPB manifest format
  • Templates for building your own extensions
  • Simple MCP server implementations for testing

But, the MCP servers themselves are not robust secure production ready servers and should not be relied upon for production use.

Examples Included

Example Type Demonstrates
hello-world-node Node.js Basic MCP server with simple time tool
chrome-applescript Node.js Browser automation via AppleScript
file-manager-python Python File system operations and path handling
calculator-rust Binary Compiled Rust binary as MCP Bundle

Usage

Each example includes its own manifest.json and can be packed with:

dxt pack examples/hello-world-node

Use these as starting points for your own extensions, but ensure you implement proper security measures before deploying to users.
